ABSTRACT:
An .alpha.-olefin polymerizing catalytic component which has a support capable of supporting a large amount of titanium and has the titanium work efficiently for polymerizing the .alpha.-olefin; and a method for carrying out homo- or co-polymerization of an .alpha.-olefin by using a catalyst system which consists of the catalytic component and an organo-aluminium compound. The catalytic component is obtained basically by allowing an organo-magnesium compound and a carbon tetrahalide to react with each other in the presence of an organic acid ester; by treating a solid product formed through this reaction with an organic compound of phenol; and then by further treating the product with a halogen-containing titanium compound.
